Inyuma EMF ya Moteri ihoraho ya moteri ihuriweho na moteri

Inyuma EMF ya Moteri ihoraho ya moteri ihuriweho na moteri

1. Nigute EMF yagarutse?

Igisekuru cyinyuma ya electromotive imbaraga ziroroshye kubyumva. Ihame nuko umuyobozi ayobora imirongo ya rukuruzi. Igihe cyose hari icyerekezo kigereranijwe hagati yibi byombi, umurima wa magneti urashobora guhagarara kandi uwuyobora arawukata, cyangwa uwuyobora ashobora guhagarara kandi umurima wa rukuruzi ugenda.

Kuri moteri ihoraho ya moteri ihuza, ibishishwa byabo bishyirwa kuri stator (kiyobora) naho magnesi zihoraho zishyirwa kuri rotor (umurima wa magneti). Iyo rotor izunguruka, umurima wa magneti ukorwa na magnesi zihoraho kuri rotor uzunguruka, kandi uzagabanywa na coil kuri stator, ubyare ingufu za electromotive mumashanyarazi.Kuki byitwa imbaraga za electromotive power? Nkuko izina ribigaragaza, icyerekezo cyinyuma ya electromotive power E ihabanye nicyerekezo cyumuriro wa voltage U (nkuko bigaragara ku gishushanyo 1).

Igishushanyo 1

2.Ni irihe sano riri hagati ya EMF yinyuma na voltage ya terefone?

Birashobora kugaragara kuva ku gishushanyo 1 ko isano iri hagati yingufu za electromotive yinyuma na voltage ya terefone munsi yumutwaro ni:

Ikizamini cyingufu za electromotive yinyuma gikorerwa mubisanzwe nta mutwaro urimo, nta kigezweho kandi ku muvuduko wa rpm 1000. Muri rusange, agaciro ka 1000rpm gasobanurwa nkinyuma ya EMF coefficient = impuzandengo yinyuma-EMF agaciro / umuvuduko. Coefficient yinyuma-EMF nikintu cyingenzi cya moteri. Twabibutsa ko inyuma-EMF munsi yumutwaro ihora ihinduka mbere yuko umuvuduko uhagarara. Duhereye kuri formula (1), dushobora kumenya ko imbaraga za electromotive yinyuma munsi yumutwaro ari ntoya kuruta voltage yumuriro. Niba ingufu za electromotive zinyuma nini kuruta voltage yumuriro, ihinduka generator kandi igasohora voltage hanze. Kubera ko kurwanya no kugezweho mubikorwa nyirizina ari bito, agaciro k'ingufu z'amashanyarazi zinyuma zingana hafi na voltage ya terefone kandi igarukira ku gipimo cyagenwe cya voltage ya terefone.

3. Ibisobanuro bifatika byingufu zamashanyarazi zinyuma

Tekereza uko byagenda iyo EMF yinyuma itabaho? Duhereye ku kuringaniza (1), dushobora kubona ko hatabayeho EMF yinyuma, moteri yose ihwanye na résistoriste isukuye, ihinduka igikoresho gitanga ubushyuhe bwinshi, ibyo bikaba binyuranye no guhindura moteri guhindura ingufu zamashanyarazi mumashanyarazi.Mu ingufu z'amashanyarazi zingana, UIt nimbaraga zamashanyarazi zinjiza, nkingufu zinjiza amashanyarazi muri bateri, moteri cyangwa transformateur; I2Rt nimbaraga zo gutakaza ubushyuhe muri buri muzunguruko, nubwoko bwingufu zo gutakaza ubushyuhe, ntoya nibyiza; itandukaniro hagati yingufu zamashanyarazi zinjiza nimbaraga zitakaza ubushyuhe ingufu zamashanyarazi, Nimbaraga zingirakamaro zihuye nimbaraga zinyuma zamashanyarazi. Muyandi magambo, inyuma EMF ikoreshwa mugutanga ingufu zingirakamaro kandi bifitanye isano no gutakaza ubushyuhe. Nimbaraga nyinshi zo gutakaza ubushyuhe, niko imbaraga zingirakamaro zishobora kugerwaho.Mu magambo, imbaraga za electromotive zinyuma zikoresha ingufu zamashanyarazi mumuzunguruko, ariko ntabwo "igihombo". Igice cyingufu zamashanyarazi zihuye nimbaraga zinyuma zamashanyarazi zizahindurwa ingufu zingirakamaro kubikoresho byamashanyarazi, nkingufu za mashini za moteri, ingufu za chimique ya bateri, nibindi.

Birashobora kugaragara muri ibi ko ingano yingufu zinyuma zamashanyarazi bisobanura ubushobozi bwibikoresho byamashanyarazi guhindura ingufu zose zinjira mumbaraga zingirakamaro, ibyo bikaba bigaragaza urwego rwibikoresho byamashanyarazi bihindura.

4. Ubunini bwingufu zamashanyarazi zinyuma biterwa niki?

Imibare yo kubara imbaraga zinyuma za electromotive ni:

E ni imbaraga za coil electromotive power, ψ ni magnetique flux, f ninshuro, N numubare wimpinduka, na Φ ni rukuruzi ya rukuruzi.
Nkurikije formulaire yavuzwe haruguru, ndizera ko buriwese ashobora kuvuga ibintu bike bigira ingaruka kubunini bwingufu zamashanyarazi zinyuma. Dore ingingo yo kuvuga muri make:

(1) Inyuma EMF ingana nigipimo cyimpinduka za magnetiki flux. Umuvuduko mwinshi, niko igipimo cyimpinduka nini nini EMF yinyuma.

. Kubwibyo, umubare munini wimpinduka, niko magnetiki flux nini nini EMF yinyuma.

.

. Kubwibyo, uko imbaraga za magnetomotive nini, niko imbaraga za magnetique zirwanya icyerekezo cya magnetique kandi nini EMF yinyuma.

(5) Kurwanya magnetique bifitanye isano no gutandukanya ikirere no guhuza pole-slot. Nini icyuho kinini cyumwuka, niko imbaraga za magneti zirwanya kandi ntoya EMF yinyuma. Guhuza pole-slot biragoye kandi bisaba isesengura ryihariye.

. Ninini ya magnetisime isigaye, niko EMF yinyuma. Agace keza kajyanye nicyerekezo cya magnetisation, ingano nogushyira magnet kandi bisaba isesengura ryihariye.

(7) Magnetism isigaye ifitanye isano n'ubushyuhe. Ubushyuhe buri hejuru, ntoya EMF yinyuma.

Muri make, ibintu bigira ingaruka inyuma ya EMF harimo umuvuduko wo kuzunguruka, umubare wimpinduka kuri buri mwanya, umubare wibyiciro, umubare wamashami abangikanye, ikibuga cyuzuye hamwe nikibuga gito, moteri ya moteri ya moteri, uburebure bwikirere, uburebure bwa pole-buke, magnetisime isigaye , ibyuma bya magnetiki byashyizwe hamwe nubunini, icyerekezo cya magnetiki icyerekezo, nubushyuhe.

5. Nigute ushobora guhitamo ingano yingufu zamashanyarazi zinyuma mugushushanya moteri?

Mugushushanya moteri, inyuma EMF E ni ngombwa cyane. Niba EMF yinyuma yarateguwe neza (ingano ikwiye, kugoreka imiyoboro mike), moteri nibyiza. Inyuma EMF ifite ingaruka nyinshi zikomeye kuri moteri:

1.
2.
3. Ubunini bwinyuma EMF bugena mu buryo butaziguye coefficente ya torque ya moteri, naho coefficient ya EMF yinyuma ihwanye na coefficient ya torque.
Duhereye kuri ibi, kwivuguruza gukurikira mubishushanyo mbonera bishobora kuboneka:
a. Iyo EMF yinyuma nini, moteri irashobora kugumya umuriro mwinshi kumurongo ugenzura mukarere gafite umuvuduko muke, ariko ntishobora gusohora umuriro kumuvuduko mwinshi, ndetse ntishobora kugera kumuvuduko uteganijwe;
b. Iyo EMF yinyuma ari nto, moteri iracyafite ubushobozi bwo gusohora ahantu hihuta cyane, ariko itara ntirishobora kugerwaho kumuyoboro umwe wumuvuduko muke.

6. Ingaruka nziza yinyuma ya EMF kuri moteri ihoraho.

Kubaho kwa EMF inyuma ni ngombwa cyane mumikorere ya moteri ihoraho. Irashobora kuzana ibyiza nibikorwa bidasanzwe kuri moteri:
a. Kuzigama ingufu
Inyuma ya EMF yakozwe na moteri ihoraho ya moteri irashobora kugabanya umuvuduko wa moteri, bityo bikagabanya gutakaza ingufu, kugabanya ingufu, no kugera ku ntego yo kuzigama ingufu.
b. Ongera umuriro
Inyuma EMF itandukanye na voltage yo gutanga amashanyarazi. Iyo umuvuduko wa moteri wiyongereye, EMF yinyuma nayo iriyongera. Umuvuduko winyuma uzagabanya inductance ya moteri ihindagurika, bigatuma kwiyongera kwubu. Ibi bituma moteri itanga umuriro mwinshi kandi igateza imbere imikorere ya moteri.
c. Kwihuta
Nyuma ya moteri ihoraho ya moteri itakaza imbaraga, bitewe nuko EMF yinyuma ibaho, irashobora gukomeza kubyara magnetiki flux kandi bigatuma rotor ikomeza kuzunguruka, ibyo bikaba bigira ingaruka zinyuma ya EMF yinyuma yinyuma, ifite akamaro kanini mubikorwa bimwe na bimwe, nkibi nk'ibikoresho by'imashini n'ibindi bikoresho.

Muri make, inyuma EMF nikintu cyingirakamaro cya moteri ihoraho. Bizana inyungu nyinshi kuri moteri zihoraho kandi bigira uruhare runini mugushushanya no gukora moteri. Ingano na flake yinyuma ya EMF biterwa nibintu nkibishushanyo mbonera, uburyo bwo gukora no gukoresha imiterere ya moteri ihoraho. Ingano na flake yinyuma ya EMF igira uruhare runini mumikorere no guhagarara kwa moteri.

Anhui Mingteng Imashini ihoraho ya Electromechanical Equipment Co, Ltd. (https://www.mingtengmotor.com/)ni uruganda rwumwuga rukora moteri ihoraho ya moteri. Ikigo cyacu cya tekiniki gifite abakozi barenga 40 ba R&D, bagabanijwemo amashami atatu: gushushanya, gutunganya, no kugerageza, kabuhariwe mubushakashatsi niterambere, gushushanya, no gutunganya udushya twa moteri ihoraho ya moteri. Ukoresheje porogaramu yubuhanga yabigize umwuga hamwe na progaramu yihariye ya magneti ya moteri yihariye yo gushushanya, mugihe cyo gushushanya moteri no gukora, ingano nubunini bwingufu za electromotive yinyuma bizasuzumwa neza ukurikije ibikenewe hamwe nibikorwa byihariye byumukoresha kugirango yizere imikorere no gutuza kwa moteri no kuzamura ingufu za moteri.
